Hi there - I’ve had my lime tree plant for about two years. I’ve never seen him this bad in the winter though! (See photo) I gave him new fertilizer this summer based on some advice from this forum and he absolutely flourished! (See second picture) As soon as I brought him inside though he started losing his leaves and the more time passes I think he might be a goner. I’m definitely a novice and don’t have anything close to a green thumb so hoping someone can help us out! Thanks!!
